Introduction

These Terms & Conditions (hereinafter the “Terms”) govern the use of the online gambling and related services provided under the brand name “Mostbet” (hereinafter “Mostbet”, “we”, “us”, or “our”). By accessing, registering an account, depositing funds, placing bets, or playing any casino, Slots, or other games available on the Mostbet website or mobile applications (collectively the “Platform”), you acknowledge that you have read, understood, and agreed to be bound by these Terms. These Terms apply to all interactions with the Platform, including but not limited to account creation, financial transactions, game participation, bonuses, and communication with our customer support. The purpose of these Terms is to ensure a transparent, responsible, and legally compliant gambling environment, with a particular focus on the protection of minors and vulnerable persons. If you do not agree with any provision of these Terms, you must immediately stop using the Platform and refrain from opening or maintaining a Mostbet account. You are also strongly encouraged to print or save a copy of these Terms for your records, as they form a legally binding agreement between you and Mostbet.

Acceptance of Terms

By creating an account or otherwise using the services provided by Mostbet, you confirm that you accept these Terms in full and agree to comply with them at all times. Acceptance of the Terms occurs when you click the relevant acceptance button during registration or when you first use the Platform, whichever happens earlier. You further agree that the English version of these Terms, as made available for players in Poland, shall prevail in case of any discrepancy or inconsistency with translations into other languages. Mostbet reserves the right to change, amend, or update these Terms at any time to reflect legal, regulatory, technical, or operational requirements. Any material changes will be posted on the Platform, and your continued use of the services after such changes have been made will constitute your acceptance of the updated Terms. It is your responsibility to regularly review the Terms so that you remain informed about any changes that may affect your rights and obligations.

Eligibility & Age Restriction (18+ only)

Use of the Mostbet Platform is strictly limited to individuals who are at least 18 years of age or above the legal age of majority in their country of residence, whichever is higher. By registering an account, you expressly confirm that you are 18+ and that you fully understand the legal consequences of participating in online gambling. Mostbet takes the protection of minors very seriously and implements technical, procedural, and verification measures to prevent underage gambling. Any attempt by a person under 18 to register or use the Platform is strictly prohibited and constitutes a breach of these Terms. If we have reasonable grounds to suspect that you are under 18, or that your account is being used by a minor, we may request age verification and immediately suspend or terminate the account until satisfactory proof of age is provided. Parents and guardians are strongly advised to monitor the online activities of minors and to use available parental control tools to prevent access to gambling websites.

Young people are at particular risk of developing problematic gambling behaviours, as they may underestimate the risks and overestimate their chances of winning. Accordingly, Mostbet strictly prohibits any marketing or promotional activity specifically targeting minors or persons who may not fully understand the risks associated with gambling. Any winnings generated from an account held by a minor will be void, and any funds deposited by that minor may be forfeited and, where possible, returned to the rightful owner or payment source. By using the Platform, you accept that Mostbet may conduct random checks at any time to confirm your age and identity, and that failure to cooperate or to provide accurate information can lead to account closure. The 18+ restriction is reiterated across our website, including banners, registration forms, and responsible gambling notices, to ensure there can be no misunderstanding about this fundamental requirement.

Account Registration

To participate in games and betting activities offered by Mostbet, you must first complete the registration process and open a personal user account (the “Account”). Registration requires you to provide accurate and truthful information, including but not limited to your full name, date of birth, country of residence, address, email address, mobile phone number, and, where applicable, preferred currency. You are required to keep this information up to date and notify us promptly of any changes, as inaccuracies may affect our ability to verify your identity, process payments, or provide customer support. Each individual is allowed to maintain only one Account with Mostbet; duplicate or multiple Accounts under the same name, household, IP address, or device may be considered a breach of these Terms. Accounts are for personal, non-commercial use only, and you may not open an Account on behalf of another person, transfer your Account, or allow any third party to use your login credentials or access your Account.

As part of our legal obligations related to Know Your Customer (“KYC”) and anti-money laundering (“AML”) rules, Mostbet may request that you provide certain identification documents both during and after registration. These may include a copy of your passport, national ID card, driver’s licence, proof of address such as a utility bill or bank statement, and, in some cases, additional documents such as a selfie with ID, video verification, or evidence of the source of your funds. You must provide such documents within the time frame specified by Mostbet; failure to do so may result in account suspension or closure. You are solely responsible for maintaining the confidentiality of your username and password and for any activity that occurs under your Account. If you suspect that your Account has been compromised, you must immediately change your password and contact customer support at [email protected] for assistance. Mostbet will not be liable for any loss or damage arising from unauthorized use of your Account resulting from your failure to maintain adequate security.

Deposits & Withdrawals

All financial transactions between you and Mostbet, including deposits and withdrawals, must be conducted in accordance with these Terms, our Payment Policy, and any applicable legal and regulatory requirements. Only payment methods that are in your own name and under your control may be used for deposits and withdrawals; payments from or to third parties are strictly forbidden and may be treated as suspicious activity. When you make a deposit, the funds are credited to your Account balance and can be used to play casino games, Slots, and other available content, subject to any running bonus conditions. Mostbet does not charge internal fees for standard deposits or withdrawals, but your bank, e-wallet, or cryptocurrency provider may apply their own charges, exchange rates, or network fees, for which Mostbet is not responsible. We reserve the right to set minimum and maximum transaction amounts for deposits and withdrawals, which may vary depending on the payment method, currency, and your country of residence.

Withdrawals are only processed to payment methods in your name, and, where possible, using the same method that was used for deposit, in line with AML and responsible gambling principles. Before processing your first withdrawal, and in some cases subsequent withdrawals, Mostbet may require successful completion of KYC verification, including proof of identity, address, and source of funds. We may also carry out checks in case of large transactions, unusual patterns, or suspected fraud. Withdrawal requests are processed within a reasonable time frame, but actual completion times depend on the payment provider and may be subject to additional security reviews. Mostbet reserves the right to delay, withhold, or cancel withdrawals if we suspect any breach of these Terms, including but not limited to fraud, chargebacks, multiple accounts, bonus abuse, or money laundering. All financial activities may be monitored and reported to appropriate authorities where required by law.

Payment Methods Table

The payment methods listed below are indicative and may vary by country, currency, and individual eligibility. Availability, limits, and processing times are subject to change and to the policies of each provider.

Mostbet may at any time add, remove, or modify available payment methods to comply with legal requirements, risk management, or business decisions. Before making a transaction, you should always check the current list of available payment options and applicable limits in your Account’s cashier section.

Bonuses & Promotions

Mostbet may from time to time offer various bonuses, free spins, loyalty rewards, tournaments, and other promotions (collectively “Bonuses”) to eligible players. All Bonuses are subject to specific terms and conditions, including but not limited to wagering requirements, minimum deposits, maximum bet limits, time validity, game restrictions, and eligibility criteria based on country or currency. By participating in any Bonus or promotion, you agree to carefully read and comply with the associated rules, which are presented on the relevant campaign page and in your Account area. Some Bonuses may require the use of a promo code, opting‑in via the cashier, or manual activation in your profile; if such steps are not completed correctly, the Bonus may not be credited. Mostbet reserves the right to grant or withhold Bonuses at its sole discretion, to limit availability to certain players, or to modify or cancel promotions if necessary for legal or operational reasons.

Unless otherwise stated, Bonus funds and any winnings derived from them remain in a bonus balance that is separate from your real money balance and cannot be withdrawn until wagering conditions have been fully met. Wagering requirements are usually expressed as a multiple of the Bonus amount, the deposit amount, or both, and must be satisfied within a defined period, after which any unused Bonus and related winnings may be forfeited. Certain games, including some Slots and table games, may contribute differently to wagering (for example, some may contribute 100%, others 10%, or 0%), and some game types may be excluded altogether; you must always check the game contribution table where provided. Bonus abuse, including but not limited to using low‑risk betting strategies, collusion, multiple accounts, or fraudulent behaviour to unlock or cash out Bonuses, is strictly prohibited and may result in cancellation of Bonuses, confiscation of winnings, and closure of the relevant Accounts. For more detailed information on current promotional offers, players from Poland may consult the dedicated section accessible via Mostbet Bonuses.

Game Rules

Mostbet offers a wide selection of games, including casino games, Slots, live dealer tables, and other interactive products supplied by reputable third‑party providers. Each game has its own specific rules, pay tables, return‑to‑player (RTP) percentages, and additional features, which are made available within the game interface or in a separate help section. Before placing real money bets, you should familiarize yourself with the rules and functionalities of each game, as your participation in a game implies acceptance of its rules. Bets placed in error or based on misunderstanding of game rules generally cannot be cancelled or refunded, except where required by law or clearly indicated in a particular game’s terms. You are responsible for ensuring that your device and internet connection are stable and suitable for online gambling, as interruptions may affect game sessions.

In case of any discrepancy between the result displayed on your screen and the records on Mostbet’s servers or on the game provider’s systems, the latter shall prevail and be deemed final. Mostbet may, at its discretion and in cooperation with game providers, adjust, void, or re‑settle bets in the event of technical failures, evident errors, or other irregularities affecting game integrity. Betting limits, including minimum and maximum stakes, are specified in each game and can vary depending on the game type, your Account status, and other factors. You agree not to attempt to manipulate game outcomes, exploit bugs, or use any external tools or scripts that may give you an unfair advantage. Any such behaviour may be considered fraud and may lead to account closure, voided winnings, and reporting to relevant authorities.

Fair Play & RNG

Mostbet is committed to providing fair, transparent, and unbiased games to all players. The outcomes of casino games and Slots are determined by certified Random Number Generator (“RNG”) technology supplied by licensed providers, ensuring that results are random and cannot be predicted or manipulated. Independent testing laboratories and certification bodies regularly audit the RNG algorithms and game payout statistics of our providers to verify compliance with industry standards. RTP values for each game are either displayed directly within the game or available in a related help document, providing players with clear information on the theoretical long‑term returns. While RTP figures provide an indication of potential returns over a very large number of bets, they do not guarantee any specific outcome or winning pattern for individual players.

Mostbet does not modify, interfere with, or otherwise manipulate the RNG or game results beyond what is necessary for technical functioning. Any suspicion of manipulation, collusion, or unfair practices by players will be thoroughly investigated, potentially in cooperation with third‑party providers and regulatory authorities. If we detect any use of bots, automated scripts, or other forms of artificial intelligence to play games or place bets, we may consider this a serious violation of fair play principles. In such cases, we reserve the right to suspend or close Accounts, void winnings, and take any other measures deemed appropriate. By using the Platform, you acknowledge that gambling outcomes are based on chance, that no system or strategy can guarantee consistent winnings, and that you are playing at your own risk.

Responsible Gambling

Mostbet recognises that while gambling can be an enjoyable form of entertainment, it also carries risks, including the potential development of problematic or addictive behaviour. We are committed to promoting responsible gambling practices for all players, particularly those in Poland, where regulations and social expectations emphasise the need to protect vulnerable individuals. Our responsible gambling programme includes a range of tools and measures designed to help you maintain control over your gambling activities, such as deposit limits, loss limits, session reminders, time‑outs, and self‑exclusion options. These tools are complemented by staff training, monitoring of risky behaviour patterns, and cooperation with professional support organisations. You are strongly encouraged to use these tools proactively, especially if you notice that gambling is having a negative impact on your finances, relationships, or mental health.

Mostbet strictly prohibits the use of its services by individuals under the age of 18, and we take additional measures to ensure that minors are not exposed to gambling content. Marketing communications are intended only for adults, and we provide responsible gambling warnings where appropriate. You should consider gambling as a form of entertainment, not as a source of income or a way to resolve financial difficulties. We recommend that you never chase losses, bet more than you can afford to lose, or gamble under the influence of alcohol or other substances that impair judgment. If at any point you feel that your gambling is out of control, you should immediately stop playing, use the Account limitation tools provided by Mostbet, and seek professional help from a recognized support organisation.

Tools & Features (table)

Mostbet provides a variety of responsible gaming tools that you can activate through your Account settings or by contacting customer support. The table below summarises the key tools and their main characteristics.

Availability of some tools may depend on your country of residence, regulatory requirements, and the current version of the Platform. However, Mostbet will at minimum offer deposit limits and self‑exclusion to all players.

Support Resources

If you suspect that you or someone close to you may be developing gambling‑related problems, we strongly encourage you to seek assistance as early as possible. Mostbet cooperates with and signposts to recognized problem‑gambling support organisations, such as GamCare, Gambling Therapy, and Gamblers Anonymous, which provide confidential advice, counselling, and self‑help resources. These organisations can offer support through online chats, helplines, group meetings, and educational materials aimed at understanding and managing gambling addiction. You can find links to these and other local organisations in the responsible gambling section of the Platform, which is regularly updated to reflect relevant services for players in Poland and other jurisdictions.

Our customer support team is trained to recognise signs of problematic gambling and may contact you if unusual patterns of play or significant changes in behaviour are detected. In such cases, we may offer information on responsible gambling tools, suggest setting more restrictive limits, or, in extreme cases, impose certain restrictions on your Account in line with our duty of care. While we take reasonable steps to promote safer gambling, ultimate responsibility for your gambling decisions rests with you. If you request self‑exclusion or time‑out, we will explain what these measures entail and what steps you should take to avoid accessing gambling services on other platforms, such as using device‑level blocking software. Responsible gambling is a shared responsibility between Mostbet and its players, based on honesty, mutual respect, and adherence to these Terms.

Prohibited Activities

To protect the integrity of the Platform and comply with legal obligations, Mostbet strictly prohibits certain behaviours and activities. These include, but are not limited to, multiple account creation; using false or misleading personal information; employing bots, scripts, or automated tools to place bets or play games; participating in collusion with other players; and exploiting system errors, bugs, or other technical vulnerabilities. Any form of fraud, including payment fraud, chargebacks, identity theft, or use of stolen credit cards or payment instruments, is strictly forbidden and may result in immediate account suspension, confiscation of funds, and reporting to law enforcement or regulatory authorities. Bonus abuse, such as using multiple Accounts, coordinated betting patterns, or other strategies to unfairly benefit from Bonus offers, is also prohibited.

Mostbet likewise bans the use of VPNs, proxies, or other technologies intended to disguise or alter your true location, especially when this is done to circumvent country restrictions or regulatory controls. Money laundering, terrorist financing, and any other criminal use of the Platform are expressly forbidden and will be reported to relevant authorities if detected. Harassment, abusive language, threats, racist or discriminatory conduct towards other players or Mostbet staff are also unacceptable and may lead to closure of your Account. You are not allowed to sell, transfer, or acquire Accounts, or to trade account balances or Bonuses in any manner. If we have reasonable grounds to believe that you have engaged in any prohibited activity, we may withhold pending withdrawals, cancel winnings, terminate your Account, and share relevant information with financial institutions, payment providers, and competent authorities where legally required.

Restricted Countries (table)

Due to legal and regulatory reasons, access to the Mostbet Platform is restricted or prohibited in certain countries and territories. The list below is illustrative and not exhaustive; it may change over time depending on evolving legislation and licensing conditions.

It is your responsibility to ensure that you are not in breach of any local laws by opening an Account or using Mostbet services from your current location. If you are found to be accessing the Platform from a restricted or prohibited jurisdiction, we may immediately suspend your Account, void bets placed during such access, and restrict withdrawal of funds, subject to applicable law and regulatory guidance.

Privacy & Data Protection

Mostbet is committed to protecting your privacy and handling your personal data in a lawful, fair, and transparent manner. We collect and process personal information such as your name, contact details, identification documents, transaction history, game records, IP address, device identifiers, and communication logs to provide you with our services, comply with legal obligations, and improve the Platform. Your data may be shared with selected third parties, including payment providers, KYC and AML verification services, game providers, analytics services, and competent authorities, strictly on a need‑to‑know basis and subject to appropriate contractual safeguards. Personal data is retained only for as long as necessary to fulfil the purposes for which it was collected and to comply with retention obligations imposed by law, typically several years after account closure.

We use technical and organisational security measures to protect your data against accidental or unlawful destruction, loss, alteration, unauthorized disclosure, or access. These may include encryption, access controls, secure storage, intrusion detection, and regular security testing. Cookies and similar technologies are used on the Platform to enable essential functionalities, enhance user experience, collect analytics, and support marketing activities, where permitted by law. You can manage your cookie preferences through your browser settings and, where available, through dedicated cookie consent tools, although disabling certain cookies may affect the performance of the Platform. As a data subject, you may have rights under applicable data protection laws, such as the right to access, correct, delete, or restrict processing of your data, as well as the right to object or to withdraw consent for certain processing activities. For more information on how we process your personal data and how to exercise your rights, you should consult the dedicated Privacy Policy available via Mostbet.

Account Suspension & Termination

Mostbet reserves the right to suspend or terminate your Account in a number of circumstances, including but not limited to suspected fraud, money laundering, use of false or stolen identity documents, underage gambling, use of VPN or location spoofing, or any other breach of these Terms. Suspension may be temporary and is often used while an investigation is ongoing; during this period, you may be unable to place bets, deposit, withdraw, or access some or all games. If our investigation confirms a violation of the Terms or applicable laws, we may decide to permanently close your Account, confiscate funds that are related to illegal or fraudulent activity, and report the matter to relevant authorities. Where possible and not prohibited by law or regulatory guidance, any remaining legitimate balance may be returned to you via an appropriate payment method, subject to verification.

You may also request voluntary closure of your Account at any time by contacting customer support, particularly if you wish to stop gambling or if you suspect that you are developing a problem. Depending on your request, we may categorize your closure as a standard account closure or as part of a responsible gambling self‑exclusion. In cases of self‑exclusion, we will take additional measures to restrict future access and to avoid sending you promotional materials. Inactive Accounts, meaning Accounts with no login or betting activity for a prolonged period, may be closed by Mostbet after prior notice, subject to regulatory requirements on dormant funds. Account suspension or termination does not relieve you of any outstanding obligations under these Terms, including cooperative duties related to ongoing investigations, KYC requests, or pending transactions.

Limitation of Liability

While Mostbet endeavours to provide a secure, fair, and continuous service, we cannot guarantee that the Platform will be available at all times or free from errors, interruptions, or technical issues. Access to the Platform may be temporarily suspended without notice in cases of maintenance, upgrades, or system failures. To the maximum extent permitted by law, Mostbet shall not be liable for any loss or damage arising from your use of the Platform, including but not limited to loss of profits, loss of data, or interruption of business, whether such losses are direct, indirect, incidental, or consequential. In particular, we are not responsible for any malfunction, failure, delay, or interruption caused by your device, internet service provider, software conflicts, or force majeure events such as natural disasters, war, strikes, or governmental actions.

If, notwithstanding the remainder of this clause, Mostbet is found liable for any claim or dispute, our total aggregate liability shall be limited to the lower of (i) the amount of your net losses on the Platform over the 30 days preceding the event leading to the claim, or (ii) a reasonable sum specified by applicable law. Nothing in these Terms shall exclude or limit our liability for death or personal injury caused by our negligence, for fraud or fraudulent misrepresentation, or for any other liability that cannot be excluded under mandatory law. You agree that you are using the Platform at your own risk and that you are solely responsible for your decisions regarding deposits, bets, and participation in games. You also acknowledge that gambling involves risk and that there is no guarantee of winning; all outcomes are determined by chance and game rules. By accepting these Terms, you waive any right to claim damages or compensation beyond what is explicitly provided herein, to the extent permitted by applicable law.

Complaints & Dispute Resolution

Mostbet aims to provide high‑quality services and to resolve any issues or misunderstandings promptly and fairly. If you have a complaint related to your Account, a financial transaction, a game outcome, or any other aspect of our services, you should first contact our customer support via email at [email protected] or through the live chat function, where available. When submitting a complaint, you must provide your Account details, a clear description of the issue, relevant dates and amounts, and any supporting evidence such as screenshots or transaction references. We will acknowledge receipt of your complaint within a reasonable period and will aim to investigate and respond substantively within a time frame consistent with internal policies and applicable regulations.

Complaints related to game outcomes may be reviewed in collaboration with the relevant game provider, using server logs and technical records as the primary point of reference. If you are not satisfied with the initial response, you may request an internal escalation or further explanation. Mostbet encourages amicable resolution of disputes wherever possible, but if a dispute cannot be resolved through our internal procedures, you may have the right to refer the matter to an independent dispute resolution body or to the competent courts, depending on applicable law. You agree to cooperate fully in any investigation, including providing accurate information and not withholding relevant facts. Frivolous, abusive, or fraudulent complaints may be disregarded or treated as a breach of these Terms.

Governing Law

These Terms, and any dispute, controversy, or claim arising out of or relating to them, to their subject matter or formation, or to your use of the Mostbet Platform, shall be governed by the laws of the jurisdiction in which the operating company behind Mostbet is incorporated, unless otherwise required by mandatory consumer protection or conflict‑of‑law rules. The choice of governing law does not affect any rights you may have under the mandatory laws of your country of residence, such as Poland, where such laws apply regardless of contractual choice. In any legal proceedings, the official version of these Terms shall be the English language version applicable to players in Poland, and any translations are provided for convenience only. You consent to the jurisdiction of the competent courts in the place of incorporation of the Mostbet operating entity, without prejudice to any right you may have under applicable consumer laws to bring a claim before courts in your country of residence.

In the event that any provision of these Terms is found by a court or competent authority to be invalid, illegal, or unenforceable, such provision shall be deemed modified to the minimum extent necessary to make it valid, legal, and enforceable, and the remaining provisions shall continue in full force and effect. No failure or delay by Mostbet in exercising any right or remedy under these Terms shall constitute a waiver of that or any other right or remedy. You agree that any claim or cause of action related to the use of the Platform must be filed within the time limits set by applicable law, after which such claims will be time‑barred.

Final Provisions

These Terms represent the entire agreement between you and Mostbet regarding the use of the Platform and supersede any prior agreements, understandings, or representations, whether written or oral, relating to the same subject matter. From time to time, Mostbet may update or amend these Terms to reflect changes in law, regulatory guidance, technical developments, or business needs. Updated versions of the Terms will be posted on the Platform and will indicate the date of the latest revision. Your continued use of the Platform after such updates have been published constitutes your acceptance of the revised Terms. If you do not agree with any changes, you must immediately stop using the Platform and request closure of your Account.

You may not assign, transfer, or otherwise dispose of your rights or obligations under these Terms without the prior written consent of Mostbet. We may assign or transfer our rights and obligations under these Terms, in whole or in part, to another entity in connection with restructuring, merger, acquisition, or other corporate transactions, provided that such assignment does not adversely affect your statutory rights. Headings used in these Terms are for convenience only and do not affect the interpretation of the provisions. By registering and using the Platform, you acknowledge that you have read these Terms carefully, understand them, and agree to be legally bound by them, and that you accept our strong emphasis on responsible, 18+ only gambling for all players using the Mostbet services in Poland and elsewhere.
